Radiance Tech Tip 16
Widescreen without an anamorphic lens
Introduction
The Radiance can be used to simplify aspect ratio control for a system, which uses a 16:9
projector to display an image on a 2. 5 screen, without an anamorphic lens.
We will setup the input aspect ratio buttons, on the Lumagen remote, to control the aspect
ratio of the projected image. The projector is left in its default 16:9 mode. The input aspect
ratio buttons on the Lumagen remote are used to set the aspect ratio.
Fixed Zoom Method
The zoom setting on a 16:9 projector is adjusted so that the image fills the width of a 2. 5
screen. The non-active image spills over the top and bottom of the screen. The projector
zoom is fixed at this setting. If you are using a 1080p projector, 1080p 2. 5 letterboxed
video sources are not scaled. i.e. When you play a Bluray 2. 5 movie, the Radiance scalier is
turned off and the image is displayed at a 1:1 ratio. The 4: and 16:9 images are scaled
down to fit inside the height of the screen. This is referred to as a “constant image height”
system.

4: The non-active image spills over the top and bottom of the screen and
wide black bars are added on both sides by the Radiance.
16:9 The non-active image spills over the top and bottom of the screen and
narrow black bars are added on both sides by the Radiance.
2. 5 The non-active image spills over the top and bottom of the screen and
wide black bars are added on both sides by the Radiance.
Procedure
This is the procedure to configure the Radiance for a system that includes a 16:9 projector
and a 2. 5 screen. This procedure requires software rev 011812 or higher and assumes that
you are starting with factory default settings. To do a factory reset press “MENU 0999” and
then press “MENU, Save, OK, OK, OK”.
1. Set the output aspect ratio by pressing "MENU, Output, Styles, [Style], Aspect Ratio, OK,
Single output aspect, OK, 2 5, OK”.

2. Set the output aspect sidebars to black by pressing “MENU, Output, Styles, [Style],
Graybar, Sides, 0%, OK”.
. Set the output shrink by pressing “MENU, Output, Styles, [Style], Mask/Shrink, Shrink,
Top:12%, Right:0%, Bottom:12%, Left:0%, OK”.
Note: If you set the projector so that the image only spills over the top of the screen, set
the output shrink to “Top:24%, Right:0%, Bottom:0%, Left:0%”.
4. Set scale bias off by pressing “MENU, Input, Options, Scale Bias, Off, All, A-D, OK”.
5. When you are finished, save the new settings by pressing “MENU, Save, OK, OK, OK".
6. Set the projector to its default 16:9 mode.
7. Set all the video sources to widescreen 16:9 output.
8. Press the appropriate input aspect ratio button on the Lumagen remote that matches the
aspect of the video input. To horizontally stretch a 16:9 image to fill the 2. 5 screen,
press “16:9” and then press “NLS”.
Variable Zoom Method
The lens zoom setting, on a 16:9 projector, is adjusted to display a 16:9 image or a 2. 5
image, on a 2. 5 screen. This is referred to as a “constant image height” system.

the non-active image spills over the top and bottom of the screen.
Procedure
This is the procedure to configure the Radiance for a system that includes a 16:9 projector

you are starting with factory default settings. To do a factory reset press “Menu 0999” and
then press “Menu, Save, Ok, Ok, Ok”.
1. If the output aspect ratio is not at the default setting of 16:9 (1.78), set the output
aspect ratio by pressing “MENU, Output, Styles, [Style], Aspect Ratio, OK, Single output
aspect, OK, 178, OK”.

5. When you are finished, save the new settings by pressing “MENU, Save, OK, OK, OK".
6. Set the projector to its default 16:9 mode.
7. Set all the video sources to widescreen 16:9 output.
8. Press the appropriate input aspect ratio button on the Lumagen remote that matches the
aspect of the video input. For a 4: , Lbox, 16:9 or 1.85 image adjust the projector zoom
so that a 16:9 image fills the height of the screen. For a 2. 5 image adjust the projector
zoom so that that a 2. 5 image fills width of the screen.
Screen With Top Maskin
A 16:9 projector is used with a 16:9 screen that has top masking. The aspect ratio of the
screen can be adjusted from 16:9 to 2. 5. This procedure requires software rev 011812 or
higher and assumes that you are starting with factory default settings. To do a factory reset
press “Menu 0999” and then press “Menu, Save, Ok, Ok, Ok”.
